Just started doing this....ive bought some steals off craigslist and made some nice ass profit margins...also my university does a "green move out" week and I help a friend organize and sort all of it...which means I get first dibs on stuff before it goes to the salvage company (name for on campus pick something leave something type student run organization)...selling some of the stuff I picked up from that too...2 mini fridges, 2 sets of crutches, a nice designer named leather jacket...etc etc...
